Application led February 25. 1913. Serial No. 750.643.

.carrying conductors and has particular' application to a ground connector whereby the ground conductors of an electric current t ansmission line may be effectively and ellin ciently connected to the ground to form the return side of the circuit.

In carrying ont the `present invention, it is my purpose to provide a ground connector for electric current carrying comluctors whereby telephone. telegraph. electric lighting and other lilies may be effectively grounded and which may be readily and easily embedded in the earth. y

It is also my purpose to produce a ground connector for electric current cariving conductors which will embrace the desired features of simplicity, efficiency. durability and convenience coupled with cheapness of cost in manufacture and inarlv'eting and which may be readily and conveniently installed in the line.

lith the aboveand other objects in view, the invention consists in the, construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim. l

In the accompanying drawing, Figure 1 is a sectional view through a portion of the earth showing my improved ground connector and conductor embedded therein. Fig. 2 vis a view in elevation of the connector, parts being broken away. Fig. 3 is an end view thereof. Fig. 4 is a fragmentary sectional view through the groundv showing the ground connector emlieddeditherein and the forcing implement removed.

Referring now to the accompanying drawing in detail. the numeral l indicates a cylindrical tube preferably composed of metal and of any suitable dimensions, snchtnbe having one end thereof threaded interiorly as at and designed to receive the exteriorly' threaded nipple 3 carrled upon one end of a metallic rod or groundk plug 4 having a.

pointed extremity 5 adapted to be inserted in the earth ornground. The conductor in conjunction with which my ground connector is employed is indicated at l and is shown as passed through the tube 1l and has the free end thereof soldered or otherwise appropriately connectedio the rod l. the nipple I on the rod being threaded into the end 2 of the tube subsequent to this connection. When the rod and tube are thus connected aunitary structure is provided which may be readily and easily passed into the ground.

My ground connector. it will be noted not only functions as a means for connecting electric current transmission comluctors to the ground but also acts as a conductor itself thereby.insuring a direct and positive connection between the current carrying wire and the ground.

ln order to elnbed or insert the conductor in vthe `ground. l preferably moisten the earth and subsequently apply a handle T to the tube l adjacent to the point of connection between the tube and the rod -l. The pointed extremity 5 ol' the rod is now forced into the earth and pressure applied to the handle T so as to force the connector downwardly. the handle being constructed in such manner as to be movable toward the upper end of the tube as the connector is worlted into the earth. lu the present instance. this handle is in the forni ol' a metal bar which is providedwith an opening between its ends through which the tube l is passed. such bar being provided with a set screw 5% adapted to be moved into the openingr therein to engage the tube and so ellect a rigid connection between the parts. A\fter the ground plug or rod l has been passed into the earth the desired distance. the tube 1 is disconnectedfrom the plug by rotating the same under they action of the handle 7. Subsequent to detaching the tube from the plufr. the former is withdrawn from the ground and slipped off the wire. the upper end of the latter remaining above the earth. the plug remaining in the earth and forming a ground connector. as clearly .illustrated .in Fig.. 4 of the drawing.

I claim:

ground connector comprising a pointed cylindrical plug. a threaded nipple formed integral with one extremity of and of a .diameter less than said plug so as to form a shoulder at their juncture.. a conducting wire secured to` Saidthreaded nipple, a tube encircling said wire und having screw-threaded engagement with said nipple, said tube having one extremity tightly engaging the shoulder formed at the juncture of the nipple with the extremity of said plug, and a handle having detachable engagement with one end portion of Suid tube.
